warum gluckert es im bauch — what are common causes?

Stomach gurgling (borborygmi) is usually harmless and results from normal movement of gas and fluid through the intestines. Common causes include peristalsis (muscle contractions moving food), swallowing air (aerophagia), gas production by gut bacteria during fiber fermentation, and hunger contractions. Certain foods (beans, cabbage, carbonated drinks) or lactose intolerance can increase noise. In most cases it's a normal physiological process. Only if accompanied by pain, diarrhea, constipation, or bloating might it indicate food intolerance, irritable bowel syndrome, or bacterial overgrowth. A MyBody-X DNA or microbiome test cannot diagnose the cause directly but may offer clues about genetic predispositions (e.g., lactose intolerance) or gut flora imbalances. For persistent symptoms, consult a doctor.
